Unless otherwise specified:
JESD22-A114 +/- 1kV Human Body Model

Signals
SIM connector
ESD protection is highly recommended at the point where the
USIM contacts are exposed, and for any other signals that would
be subjected to ESD by the user.

Environmental Specifications
The environmental specification for both operating and storage conditions are defined in the table
below.
Table 4.
Environmental Specifications
Conditions
Range
Operating Class A
-30°C to +70°C
Operating Class B
-40°C to +85°C
Storage
-40°C to +85°C
Note:
The upper limit of Class A is subject to module PCB temperature. A progressive 3G output power
reduction feature is implemented for when PCB temperatures are above +80°C. This leads to a
calibrated 3G TX power output up to +80°C for the PCB temperature and automatic decrease at
higher temperatures. Therefore, depending on module activity and customer design, the upper limit
of Class A could be lower than 70°C.
Class A is defined as the operating temperature ranges that the device:
Shall exhibit normal function during and after environmental exposure.
Shall meet the minimum requirements of 3GPP or appropriate wireless standards.
Class B is defined as the operating temperature ranges that the device:
Shall remain fully functional during and after environmental exposure
Shall exhibit the ability to establish a voice, SMS or DATA call (emergency call) at all times
even when one or more environmental constraint exceeds the specified tolerance.
Unless otherwise stated, full performance should return to normal after the excessive
constraint(s) have been removed.
